1-ESS1-2   Earth's Place in the Universe

Students who demonstrate understanding can:

1-ESS1-2. Make observations at different times of year to relate the amount of daylight to the time of year. [Clarification Statement: Emphasis is on relative comparisons of the amount of daylight in the winter to the amount in the spring or fall.] [Assessment Boundary: Assessment is limited to relative amounts of daylight, not quantifying the hours or time of daylight.]
The performance expectation above was developed using the following elements from the NRC document A Framework for K-12 Science Education:

## Science and Engineering Practices

### Planning and Carrying Out Investigations

Planning and carrying out investigations to answer questions or test solutions to problems in K–2 builds on prior experiences and progresses to simple investigations, based on fair tests, which provide data to support explanations or design solutions.

## Crosscutting Concepts

### Patterns

Connections to other DCIs in first grade: N/A
